Bullet diameter on a 38 is .357; on a 380 it is .355 Case is longer on a 38.
The case of the 9x18 cartrdige is 1mm longer and the slug is slightly wider. In metric .380 ACP is 9x17.
The 38 special will be in a revolver and the 380 ACP most probably a semi-auto. However some of the energy of the bullet is used to eject and reload the 380 which dampens the recoil a bit. Also the .38 special is actually 0.357 " diam and the 380 is 0.355". The upshot of it all is that the .38 would have more recoil.
I could not find any 380 cal. pistol going back to 1887 ??? are you sure it's not a 38 cal. revolver ???? check writting on top of barrel ......................
There are several different types of .38 cartridges. The main thing which separates the .380 from the rest of them is that the .380 is intended for use in an unlocked breech pistol, whereas most of the other rounds are too powerful to be used in such a pistol. The .380 has a bullet diameter if .355 inches, and the metric designation for the cartridge is 9x17mm. The most common .38 cartridge would be the .38 Special, which has a bullet diameter of .357 inches, has a longer case, and the most obvious difference is that it uses a rim, as opposed to the rimless design of the .380 ACP. You may also have the .38 Super in mind, which is a cartridge intended for autoloading pistols, and still remains popular with competition firers. It has a bullet diameter of .356 inches, has a 22.83mm case length (vs. the 17.3mm case length of the .380), and much higher chamber pressures than the .380 ACP, making it unsuitable for the simple, unlocked breech pistols of the type commonly chambered for cartridges such as the .380 ACP.
10% of 380 is 38. 380 + 38 = 418 or 380 x 1.1 = 418
The most common .38 is the .38 Special, a rimmed revolver cartridge that is actually .357 inches in diameter. The most common .380 is the .380 ACP. That is a rimless automatic pistol cartridge. It is shorter and slightly fatter than the .38 Special. They are intended for two entirely different firearms, and do not interchange.
Two different sizes. .32 is .320 inches in diameter, .380 is, well, .380. There are different .32 cartridges for revolvers and automatic pistols, the .380 is for automatic pistols. The .380 also has more power than a .32 auto.
thirty-eight 380 / 10 = 38
